I wanted to add a thumper to my 8-gallon still (from Mile Hi) with 3 inch lid/column. Mile Hi custom-built this 3-gallon thumper with a 3 inch pot still head to fit my existing unit, ,and I couldn't be more pleased. The craftsmanship is outstanding, and it fit perfectly with my existing setup. The quality of the materials and build is top-notch. What truly stood out was the excellent customer service – responsive, helpful, and they delivered the product in just six days! I highly recommend this company for anyone looking for anything to do with a still. Absolutely worth every penny!
